The Lowdown
Alright folks, Rusty here. Let’s get into it for Kennebunk Beach.
Right off the bat, I’ll be straight with you—this 16-day window is a tough one for paddle surfing. We’ve got a long stretch of flat to tiny, weak waves, and when the swell does show a pulse, it’s often messy or blown out. The water's sitting at a touch warmer than normal for this time of year, about 67°, so at least it’s comfortable to sit out there waiting for something that rarely comes.
The first real glimmer of hope doesn’t arrive until early on Sunday, September 6th. Early that morning, we see a jump in swell to 6 ft from the ENE, with a period of 8 seconds and a combined energy of 447 (moderate). The wind is offshore from the NE at 9 mph, keeping things clean. That’s the standout session of the whole forecast—clean, fun-sized waves with a bit of kick. The swell direction (ENE) isn’t the optimum (ENE) for the break, so it’s hitting the right angle. Expect crowds to be possible, as it’s the only real window. The afternoon that same day gets onshore and messy, so don’t sleep in.
There’s a brief pulse on Thursday afternoon, September 3rd, with 7 ft from the SSE, but the period is a short 7 seconds and the wind is cross-shore. That’s expert territory at that size, and the quality is marginal. The combined energy hits 609 (strong), but it’s a short-period, lumpy affair.
After that, it’s back to small, weak, or flat conditions. The second week is particularly quiet—tiny 1 ft to 2 ft leftovers with poor winds and hardly any energy. Nothing worth paddling out for.
Overall, a pretty blank run for Kennebunk Beach. It’s a sheltered setup, so it tends not to stay poor for long, but this stretch is a long one. Best bet is to mark Sunday morning, September 6th, and hope the forecast holds.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
